I can only claim three days experience but in that time I wasted many hours answering almost 2000 questions only to have my entire profile vanish.
Next day I tried to log in and it said "account deleted"
Today I created another account because I wanted to use the forum to find help. You can read problems others had in the forum but you cannot post unless you log in. When you do log in you cannot access the forum... it just redirects you back to the home page. Basically you cannot complain about problems.
10 minutes after creating the account ( no info in profile yet) I went back to log in and it said "account deleted"?
Now several hours I can again log in to the test account but my primary account still says "deleted".
These are classic signs when a company like this is in trouble and about to close its doors, technical problems go unresolved, forums and blogs are disabled for comment, support emails go unanswered.
I won't waste those hours again. If they fix the problem and I can finally access my account again and have not lost that work I will give it a try. But if they lost everything then I give up.
A site like this, hype aside, is useless if it does not function and they won't fix it.
Well now that I created a new account in order to try to gain access to forums to complain, that account was also deleted. Bottom line, these people refuse to let anyone complain about anything. If you do you will not get any response or support, they will simply delete your account without any warning or explanation.
